As stated, CGiX has the capacity to build the complete history of a portfolio with only acquisition, disposal and optional event information, although this is by no means the only method of migrating data onto the system.

CGiX is also able to duplicate the exact history that a client holds in their IMS without modification. As such, CGiX aligns precisely to our clients' objectives, whether they wish to clean and amend or simply retain their historic data.

At the interface, portfolio transaction information can be divided into three distinct categories; Purchases and sales, Corporate events and Take-on / other account events.

For the most accurate reconciliation of portfolios between CGiX and host investment management system, all transactions should be passed through the CGiX interface. Any transaction types that are not deemed relevant can be set for exclusion and will not then be processed.

As a basic minimum requirement Purchases and Sales must be passed through the interface. In this configuration both compulsory and optional corporate event transactions can be auto-generated with CGiX providing basic offers where alternatives exist. Where optional events are also provided, and the transactions describing participation in corporate events received, CGiX can intelligently represent a portfolio using these transactions to describe alternative offer take up, election for option distributions and 'Mix 'n' match' elections.

• Currency movements are correctly calculated within CGiX
• Transactions may be marked as suspect or estimated if the true cost is unknown
• Transactions may also be marked as fixed values where reconciliation is not made within the terms of a corresponding corporate event.

Holdings are used for reconciliation purposes only. Once client and portfolio transaction data has been imported through the interface and calculations have been run on affected portfolios, a reconciliation process is undertaken against the portfolio holdings data received.

Prices are used to prepare valuations and 'What-If' enquiries. Imported security prices do not affect CGT calculations or chargeable gains.

During the initial implementation of CGiX the full security universe of all portfolio holdings is matched against the CGiX security universe on security identifiers (SEDOL, ISIN, bespoke codes etc.).

As all transactions must have an underlying security it is important that the security identifier is recognised by CGiX. Reconciling against the security universe of the host Investment Management System ensures that all securities are identified correctly.
